Josephson current in ballistic Nb/InAs/Nb highly transmissive junctions
Francesco Giazotto, Kasper Grove-Rasmussen, Rosario Fazio +3
Highly transmissive ballistic junctions are demonstrated between Nb and the two-dimensional electron gas formed at an InAs/AlSb heterojunction. A reproducible fabrication protocol…

Resonant Tunneling Spectroscopy of Interacting Localised States -- Observation of the Correlated Current Through Two Impurities
V. V. Kuznetsov, A. K. Savchenko, D. R. Mace +2
We study effects of Coulomb interactions between localised states in a potential barrier by measuring resonant-tunneling spectra with a small bias applied along the barrier. In the…

Tunneling Between Two-Dimensional Electron Gases in a Weak Magnetic Field
N. Turner, J. T. Nicholls, K. M. Brown +4
We have measured the tunneling between two two-dimensional electron gases (2DEGs) in weak magnetic fields, when the carrier densities of the two electron layers are matched. At zer…
